Question

    `IF(@ParentField = 'Reason for call - Primary Issue')
    BEGIN
        DELETE FROM dbo.ControlBrandMapping CBM
            INNER JOIN dbo.ControlManagement CM ON CM.ID = CBM.CONTROLID
                WHERE CM.DefaultName = 'Reason for call - Sub Issue' AND CBM.BRANDID = @BrandId
    END`

我尽力让它看起来尽可能整洁。我收到此错误 - “'CBM'附近的语法不正确。” 请帮忙

Answer 1

您在CBM子句后缺少别名DELETE。试试这个：

    DELETE CBM
    FROM dbo.ControlBrandMapping CBM
    INNER JOIN dbo.ControlManagement CM ON CM.ID = CBM.CONTROLID
    WHERE CM.DefaultName = 'Reason for call - Sub Issue' 
      AND @ParentField = 'Reason for call - Primary Issue'
      AND CBM.BRANDID = @BrandId

Answer 2

我对此并不确定，我刚刚开始，但据我所知，在做加入时，我认为它应该是INNER JOIN dbo.ControlManagement CM ON (CM.ID = CBM.CONTROLID) 注意括号，但我可能错了
